PROBLEM TO BE SOLVED: To provide railroad ballast, the ground of a structure, and construction methods thereof for effectively preventing the occurrence of frost heave on the railroad ballast and the grounds of various structures, effectively utilizing industrial waste and low in construction cost. SOLUTION: In this construction method, a construction material obtained by mixing clinker ash and a frost heaving material so that the weight ratio of the clinker ash to the total weight of the clinker ash and frost heaving material is≥50% and <100%, is used for the railroad ballast 2 and the grounds of various structures to carry out construction. It is preferable to mix the clinker ash to have the ratio of≥70% and <95%. The frost heaving material is gravel including fine grain portions, sand, crushed stones adjusted in grain size, or the like. COPYRIGHT: (C)2006,JPO&NCIPI
